A drive class of its own



SINAMICS S120 Combi offers the tried-and-tested SINAMICS functionality with an integrated drive concept specifically matched to compact turning and milling machines. With a multitude of technical highlights, SINAMICS S120 Combi sets new standards in this drive class.
SINAMICS S120 Combi combines regenerative power supply as well as 3 or 4 motor modules for spindle and feed motors in one power module. In addition, SINAMICS S120 Combi features a connection terminal for a TTL encoder. This facilitates the spindle encoder’s direct and cost-efficient connection without additional hardware.

18 / 5 / 5 A,  24 / 9 / 9 A,  30 / 9 / 9 A
With 4 motor modules:
18 / 5 / 5 / 5 A,  24 / 9 / 9 / 9 A,  30 / 9 / 9 / 9 A

SINAMICS S120 Combi - Benefits

SINAMICS S120 Combi offers maximum performance in minimum space:

  • Optimum dynamics and precision in a compact and integrated drive design
    with valuable features such as Dynamic Servo Control (DSC), 80-bit NANOFP accurancy an a high speed DRIVE-CLiQ communication interface

  • Uncompromising rugedness
    caused by optimum protection against condensation,
    insensibility against weak power supply and
    protection against short circuit, overvoltage and ground faults.

  • Perfectly expandibility
    by easy connection of up to two additional SINAMICS S120 motor modules and
    by arbitrarily interpolation of the additional axes with the axes of SINAMICS S120 Combi.
